chevron servise station chevron service stations puts $125.00 charge on debit card for $37.00 of gas !!! Internet

so i went  to a chevron station located at 2500 Highway 52 E, Pelham, AL 35124  and used my debit card and bought $37.00 worth of gas. later in the day my wife called me and asked me what i spent $125.00 on in pelham this morning.i told he i only got $37.00 of gas. i told her to call the bank and she did and way told that at the same time i bought gas a $125.00 charge was also place on my debit card. the lady says it happens all the time with chevron.well we didnt have enough money in our account for an extra $125.00 to be take out and if we bounce some bill im suing this chevron.the lady at the bank said to come in and fill out some paper work for fraud and they will dispute the charge. i will never spend a dime at a chevron gas station for as long as i live.
